.To all whom 'it may cioncem:-

Be it known that we, ORLANDO B. HOOVER and MONROE CURRY, citizens of theUnited States, and residents of Killeen, in ,the county of Bell andlState of Texas, have made certain new and useful Improvements inMachines for Filling Brushes, of which the following is a specification.

Our invention is an improvement in machines for filling brushes, andconsists in certain novel constructions, and combinations of parts,hereinafter described and claimed. l

The object of the invention is to provide a simple ellicient machine ofthe character specied which will be especially adapted for filling withbristles, brushes for clothes, hair, or gins, and for securing thebristles in the'article.

Referring to the drawings forming a part hereof, Figure 1 is a frontview of the improvement partly in section, Fig. 2 is an enlargedsectional view of a portion of Fig. 1 showing the mechanism in oneposition, Fig. 3 is a similar view showing the mechanism in anotherposition, Fig. 4 is an end view of the improvement with the brush partlyin section, Fig. 5 is a similar view of the lower portion of Fig. 4showing the cam in another position, and Fig. 6 is an edge view of thecam. t

In the embodiment of the invention shown in the drawings, a supportingframe is provided, the said frame consisting of end plates 1, and atable2 supported by the end plates, the bottom of the said plates beingconnected by rods 3, one of the ends of each rod being threaded andengaged -by a nut 4.

Each of the end plates 1 is provided near its lower end with a bearing5, and a shaft 6 is journaled in the bearings. The ends of the shaft areextended beyond the end plates, and one of the ends is rovided with apulley 7 loosely journaledD thereon, .while the other is provided with acrank disk 8 secured thereto. f

The hub 9 of the pulley is provided with clutch teeth 10 at its innerend, and a sleeve 11, slidable on the shaft but constrained to rotatetherewith, is provided with clutch teeth meshing therewith, when the-sleeve is moved toward the pulley. The sleeve is provided with anannular groove l2, and a lever 13 is pivoted to an arm 14 on the adjacent end plate, and is provided with a fork 15 engaging the groove. Theopposite end pulley may be connected and disconnectedwith the shaft.

Intermediate its ends the shaft is provided with a crank arm 17,and-adjacent to the pulley 7 a bevel gear wheel 18 is secured to theshaft by a set screw 19. A vertical shaft 20 is journaled in bearing arm21 on' the end plate adjacent to the pulley, and in a bearing 22 in thetable and its lower end is provided with a bevel gear wheel 23 meshingwith the bevel gear 18. The upper end of the shaft 2O extends above thetable 2, and is provided with a crank vdisk 24, and directly above thecrank arm 17, a cylinder 25 is secured to the under face of the tabletop by means of nuts or bolts 26, passing through an annular flange 27on the cylinder and engaging the table. A pair of arms 28 extenddownwardly from the lower end of the cylinder, and each is provided witha bearing 29 engaging the shaft 6, one bearing being upon one side ofthe crank arm, and the other bearing on the other side. A piston 30 ismovable in the cylinder, and a pitman or piston rod 31 connects thepiston with the crank. p

The cylinder is provided at one side near its upper end with an outletpipe 32, and on the other side with an outlet valve. rlhe said valvecomprises a nipple or cage 33 ar ranged over an opening 34 in thecylinder, and a valve 35 normally closes the opening and is providedwith a stem 30 passing through the outer end of the cage. The st-em isalso provided with a collar 37, and a spring 38 is arranged between thecollar and the end of the cage, and normally holdsI the valve closed,but permitting it to open when the piston moves upwardly.

A small cylinder 39 is arranged on the top of the table at the endadjacent to the crank disk 8, and the pipe 32 is provided with an elbow40 leading into the cylinder. A nozzle 41 is fitted tightly but slidablyl,into the outerend of the cylinder and is Yprovided with a pin 42extending through a slot 43 in the cylinder. A link 44 is provided ateach end with an opening, one fitting over the pin 42, and the otherover the wr1st pin 45 of the crank disk 24.

A washer 46 is arranged on t-he pin 42 below the link, and a key 47traverses the 'pin above the link. It will be evident that when Vthecrank disk 24 rotates, the nozzle will be on the under side. A magazineor holder 54 for the bristles 55 is arranged beyond the nozzle, and themagazine is provided with a flanged opening 56 in its side, throughwhich the reduced portion of the nozzle passes when it is inthe positionshown in Fig. 2.

The table 2 is extended beyond the end plate toward and against themagazine as shown, and is provided with an opening 57 directly below theopening 56, and in the space below the extension, and between the endplate and the magazine, the articles 58 to be filled with bristles areplaced, with the openings 59, for the bristles in register with theopening 57.

A needle holder` 60 is Slidable vertically in bearings 61 on the endplate, and is provided in its upper end with an opening for receivingthe needle 62, which is secured in place by a set screw 63. The needleis provided with an eye 64 for receiving the twine 65, and the holder isreciprocated by'means of` a pitman or link 66, connected at one end withthe wrist pin 67 of the crank disk 8, and at the' other to a pin 68 onthe needle holder, a key 69 passing through the pin to hold the pitmanin place.

The needle is operated by means of a shaft 73, .journaled longitudinallyof the frame near the bottom thereof and having secured to one endoutside of the frame a disk 74, provided with a wrist pin 75, and a link76, connects the wrist pin with the needle holder 60. A cam wheel 77 isalso secured to the shaft between the disk and the frame 1 and the saidwheel is provided with two cams 78 and 79. A lever 80 is provided atapproximately its center with a longitudinal slot 81, which is engagedby a pin 82, on the frame and near its lower end'the lever is providedwith an angular portion or arm 83. A spring 84 is connected at one endwith a pin 85, on the lever and at the other lwith a frame and normallyholds the lever in the position shown in Fig. 4. The upper end of thelever is pointed as shown at 86, to enter the openings 59 for receivingthe bristles 55. By means of the cams 7,8 and 79, a vertical movement isimparted to the lever 80, and also a vibrating movement on the pin 82.The needle holder 60 is slidable in bearings 87 on the frame, and .aneye 88Ais provided on the frame adjacent to the needleholder throughwhich the twine passes before it I reaches the eye on the needle holderand the eye 88 is slightly /below the eye 70, when the needleholder isin its upper-most position.

In operation, the holder being filled with bristles, the shaft 6 isclutched to the pulleyTA which is connected with any suitable source offpower. The rotation pf the shaft creates a vacuum in the cylinder 25,since the air is free to pass outthrough the valve, but is not permittedto enter. The nozzle is moved toward the holderv or magazine, and entersthrough the opening 56. The needle mean'- while has moved upward, andthe reduced portion of the nozzle passes through the loop of thread-formed in the thread. The reduced portion passes on into the holder,and just as it is well entered the lateral opening 49 comes intoregister with theelbow 40, and the air rushesthrough the opening 53 ofthe nozzle to fill the vacuum in the` cylinvder 25. The current of aircarries a tuft of bristles with it, and the bristles enter the reducedportion until the ends thereof engage the shield or stop 51. The nozzlecontinues its outward movement until the tuft assumes a positiontransverse to the opening 57 in the table. The needle during the abovedescribed movement Aof the nozzle has' moved downward, and the tensiononthe twine or thread 65 draws the bristles through the opening 59 ofthe article 50, in a doubled condition as shown in Fig. 3.

The above described process is repeated for each opening of the article,until it is filled with bristles, the article being moved as the fillingprogresses. Any suitable tension means may be provided for the thread,and it is passed through a guide eye 70 on the holder to the needle.

A stirring rod or needle 71 is secured to the pitman 66 as at 72, andpasses upwardly through an opening into the holder. The needle assistsin feeding the bristles downward in the magazine. When the machine is inoperation, the cam 79 strikes the lateral arm 83 (see Fig. 5)raising-the lever 80 and causing the point 86 to enter one oftheopenings 59 in the brush. As the point enters the opening the cam 78strikes the lower end of the lever, and moves the said lower endlaterally, thus feeding the brush 58 laterally and bringing anotheropening into position to be filled with bristles.
